ldEANS F04." INJECTING LIQUID OB GASEO'US MIATTER UNDER PRESSURE INTQ MEETS. OR THE LIKE.

Application filed August 29, 1921.

To all whom it may concern:

Be it known that T, Gnone Sonnrn, engineer, residing at Berlin, 0. 27, Germany, 18 Marcusstrasse, have invented certain new and useful Improvements in Means for In jecting Liquid or Gaseous Matter Under Pressure into Meat or the like, of which the following is a specification.

For pickling and preserving meat or the like it is usual to introduce a perforated clyster-pip-e or similar injector pipe or even an ordinary nozzle through which the preserving matter is introduced into the meat to be treated. More especially when use is made of high pressures it is necessary that the instrument for the injection of the pre serving matter be so secured and rendered stench in the meat as to prevent its retroces ion as also the escape of the preserving substance along the nozzle or the like by reason of the application of the high pressure. This securing and stanch-holding has hitherto been effected in more or less cumbersome and unsatisfactory manner, for example by means of cords, guards, projections on the nozzle which sometimes are of screw-formation; frequently special fastenand stanclrmaking means are renounced of. This invention makes use of the natural elasticity of the meat in the fastening and stanch-making of the instrument therein; it is characterized in that the fastening and stanchness of the instrument is obtained with the aid of a graduated cone and pressure-disc. For this purpose the nozzle or the like is fitted at its rear end with an easy cone which the nozzle is inserted into the meat so as to entirely lodge therein and have an overstanding layer of the meat at its rear. The portion of meat at the rear of the base of the cone contracts owing to its innate elasticity and, by means of a pressure-disc, is firmly gripped between the base of the cone and the disc whereby a secure attachment of the instrument in the meat is obtained on the one hand and stanchity of same on the other hand.

The drawing shows the invention; a denotes the pointed and perforated nozzle proper which is engaged in the long drawn Specification. of Letters Patent.

cone 6 having a recessed base. The extension piece 0, screwed into the cone 6 carries a slidable recessed pressure-d1sc and the fixed screw-threaded rings 6 and 7. The

round nut 9, adjustable by means of the threads on the ring 6, pressed the disc cl against the recessed base of the cone Z). The threads on the ring 7 serve to receive a union-nut of the pressure-hose.

For the purpose of using the instrument, the nozzle a is introduced into the meat so that the base of the cone 6 is suitably covered by meat, whereafter the nut g is screwed towards the cone 5 to thereby press the disc (Z into the meat and gripping the meat between the base of the cone 6 and disc (Z in such a manner as to prevent the pres-' sure in the nozzle from either ejecting the instrument from the meat or the preserving matter along the nozzle.

The pressure on the disc cl may also be exerted by spring-power or in any other manner.

We claim:

1. An instrument for injecting a preserving fluid into meat or the like, comprising in combination a hollow needle having a plurality of lateral apertures and being adapted to be introduced into the food to be preserved; an inverted conical member ailixed to said needle above said apertures; a washer arranged upon the needle above said conical member; and a nut also arranged upon the said needle above said washer, as set forth.

2. An instrument for injecting a preserving fluid into meat or the like, comprising in combination a hollow needle having a plurality of lateral apertures and being adapted to be introduced into the food to be preserved; an inverted conical member affixed to said needle above said apertures; a washer arranged upon the needle above said conical member; an externally threaded ring affixed to the needle shaft above said washer; and a nut surrounding said ring and being adapted to be turned downwards and upwards upon it, as set forth.
